Wiseco BMW 2.3L S14B23 1.1897CH -5cc Dish Piston Kit (Built to Order)

When you're rebuilding the heart of your 1988-1991 BMW M3 for serious racing, you need components that can handle the stress. This piston kit from Wiseco includes four forged pistons, precision-machined for the S14B23 engine. These aren't your average pistons; they're built for heavy to severe duty performance applications, meaning they're designed to take a beating on the track and keep going.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-performance engines. You'll notice features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements, all working together to ensure a solid seal and efficient combustion. The fully machined crown and forced pin oiling are thoughtful touches that contribute to the overall durability and longevity of the engine. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, making for a smoother, quieter operation even under extreme conditions.

Because these are built to order, you're getting a set tailored for your specific needs. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious build, consider pairing these with other high-performance engine components to maximize your M3's potential.
